To all whom it may concern:

Be it known that I, EDWARD HEYLYN, a citizen of the United States, residing at Manchester, in the county of Hartford and State of Connecticut, have invented a new and useful Pavement, of which the following is a specification.

This invention relates to a pavement for -highways, parkways, gangways, and other ways and Walks which are subject to heavy traffic and are liable to become slippery;

' The object of this invention is to provide a pavement which is simple to construct and easy to lay, which is very durable and impervious to water, which will not vary under extremes of tem erature, and which provides. a surface two different densities, so

that slipping is avoided.

This invention resides in a pavement which is formed of supporting-blocks of one density and locking and cushioning blocks of a different density arrangedso as to form a inodorous, and does not soften under the rays of the summer sun.

In the dovetail grooves between the wear -56 ing-sections and resting on the bases so as to overlap the longitudinal and transverse joints of the supporting-blocks are placed dovetail blocks 5, which are preferably made of wood; but of course they may be formed of other substances, if desired. These blocks if of wood are usually cut so that the rain extends vertically, and they are refera ly a little narrower at the top than t e openings between the composition blocks, and in the spaces between the elastic wooden blocks and the hard composition blocks an asphalt composition or a resinous composition is poured to fill the cracks and look the blocks I together. 1 V v Such blocks as are shown and described herein are simple to make, and it iseasy to lay them in place so that they interlock and hold each other firmly in position. The

smooth alternating surface of the two substances,'whereb permanency is insured, the noise of the traffic is reduced, and a sure foothold is provided for animals.

Figure 1 of the accompanying drawings shows a perspective view of a small area of pavement which embodies this invention. Fig. 2 shows a vertical section on larger scale, taken through a fewof the blocks.

This pavement is laid upon any common substantially laid concrete foundation 1.

wood forms a cushion for the composition, 7e and the composition protects the \wood against wear, and at the same time a smooth surface is rovided which at intervals is of different elasticity, so that a horse can obwhen thepavement is wet.

The invention claimedis- A com ound pavement formed of abutting bloolis of hardened plastic compound, each block having a wide fiat base and a tain a foothold and will not be inclinedto slip 7 5 l gravel, as desired. This material when .mixed and hardened is impervious to water,

dovetail wearing-rib narrower than the width but as long as the length of the base, extending upwardly from the middle thereof, and dovetail locking-strips of wood lying be tween the wearing-ribs and overlapping the*8 5 4 longitudinal and the tiansverse joints so that each stri rests upon sections of the bases of four locks, substantially as speci fied.
